Ditto. Definitely a Chrysler M-Body and NOT a LTD. A LTD would have turn signals that wrap around the front fenders, and a more slanted rear window.

Besides, the NYPD fleet was pretty much just Chryslers through the 1980s (where the game takes place) - Plymouth Volares in the early 80s, and Plymouth Gran Furys/Dodge Diplomats from the mid to late decade. They didn't get Fords until the mid-90s Crown Vics (and even then, they relied much more on the Chevy Caprice).

This could either be a Dodge Diplomat or Plymouth Gran Fury - can't really tell them apart from that angle and with that resolution.
